One of the great joys of exploring other cultures is seeing how other people eat — but sometimes, you need a strong stomach to deal with what you find. Around the world, people eat fried tarantulas, sheep's heads, duck embryos, and tons of other weird items. Here are the strangest and most revolting food items on Earth.

Balut, a developed duck embryo boiled alive and eaten in its egg. Really common in Southeast Asia and often served with beer.

Casu Marzu, (means rotten cheese) a traditional sheep milk cheese from Sardinia, Italy. The cheese makers set the cheese outside and allow cheese flies to lay eggs inside of it. The larvae are breaking down of the cheese's fats and fermenting it.

It's unnecessary to clear those white worms from the cheese before consuming, but some people do it. The Casu Marzu was banned for years and only sold on the black market, but few years ago it was declared a traditional food and now it's legal to produce and sell them.

The recipe is really simple: put 300-500 Auks into the hollowed-out body cavity of a seal and press out as much air as possible. Cover the seal with a large rock pile for 3-18 months and eat the Auks raw.
